Abstract: A multi view backlight and multi view display employ an optical mask element having a first portion and a laterally displaced second portion to mitigate Moiré associated with the optical mask element. The multiview backlight includes an array of multibeam unit cells distributed across a light guide. Each multibeam unit cell has a multibeam element configured to scatter out a portion of guided light as a plurality of directional light beams having different directions corresponding to different views of the multiview display. Each multibeam unit cell further includes an optical mask element having the first portion aligned and co-extensive with the multibeam element and the second portion laterally displaced within the multibeam unit cell from the first portion. One or both of the lateral displacement and an overall size of the optical mask element is configured to mitigate Moiré associated with the optical mask element.

Abstract: A grating-coupled light guide concentrates light and diffractively redirects the concentrated light at a non-zero propagation angle as guided light having a predetermined spread angle. The grating-coupled light guide includes a light guide, an optical concentrator, and a grating coupler. The optical concentrator is configured to concentrate light from a light source as concentrated light and the grating coupler is configured to diffractively redirect the concentrated light into the light guide as the guided light. Characteristics of the optical concentrator and grating coupler are configured in combination to determine the non-zero propagation angle and predetermined spread angle. A grating-coupled display system further includes an array of light valves configured to modulate emitted light as a displayed image.

Abstract: A multilayer static multiview display and method of multilayer multiview display operation provide a plurality of multiview images using diffractive scattering of light from guided light beams having different radial directions. The static multiview display includes a first multiview display layer configured to emit directional light beams representing a first multiview image by diffractive scattering light from a radial pattern of guided light beams within the first multiview display layer. The static multiview display further includes a second multiview display layer configured to emit directional light beams representing a second static multiview image by diffractive scattering light from a radial pattern of guided light beams within the second multiview display layer. The provided plurality of multiview images may include a composite color multiview image, a static multiview image, or an animated or quasi-static multiview image.

Abstract: Multiview backlighting having a color-tailored emission pattern provides directional light beams corresponding to a plurality of different views of a multiview image. A multiview backlight includes a light guide configured to guide light as guided light and a color-tailored multibeam element. The color-tailored multibeam element is configured to provide emitted light having the color-tailored emission pattern from the guided light. The emitted light includes a plurality of directional light beams having different principal angular directions corresponding to respective different view directions of a multiview display. The color-tailored emission pattern corresponds to an arrangement of color sub-pixels of a view pixel in the multiview display.

Abstract: A polarized backlight employs a light source configured to provide polarized light and a light guide to guide the polarized light. A polarization-preserving scattering feature optically coupled to the light guide is configured to scatter a portion of the guided polarized light out of the light guide as emitted polarized light. A polarization of the emitted polarized light is determined by a polarization of the guided light.
